Fig. 15.—(_a_) Line Lattice-work Surface Pattern, produced by the repetition of either the Chevron Border, Fig. 2 (_a_), or the Lozenge Border, Fig. 2 (_b_). (_b_) The same as (_a_), but shaded. Fig. 16.—(_a_) The same as Fig. 15 (_b_), but with shaded Lozenges of two different sizes. (_b_) Lattice-work Surface Pattern; the same as Fig. 15 (_b_), but with diagonal white bars instead of lines. [Illustration: Fig. 17.] [Illustration: Fig. 18. Fig. 17.—(_a_) Bar Lattice-work-Surface Pattern; the same as Fig. 15 (_a_), but with diagonal bars instead of lines. (_b_) The same as (_a_), but shaded. Fig. 18.—(_a_) Surface Pattern, produced by repeating Fig. 11 (_c_). (_b_) The same as (_a_), but shaded. ] The patterns derived from the saltire are shown on Fig. 19. [Illustration: Fig. 19. (_a_) Saltire Border Pattern. (_b_, _c_, _d_) Saltire Border Pattern, shaded in different ways. (_e_) The same as (_a_), but with bars instead of lines. ] The patterns derived from the hexagon are shown on Figs. 20 and 21. [Illustration: Fig. 20.] [Illustration: Fig. 21.] Fig. 20.—(_a_) Hexagon Border Pattern, derived from the Lozenge Border, Fig. 2 (_b_), by leaving out every other =X=. (_b_) The same as (_a_), but with the Triangles shaded. (_c_) The same as (_a_), but with the Hexagons shaded. (_d_) Surface Pattern, composed of Hexagons and Triangles; produced by repeating (_c_), so that the Hexagons in one horizontal row adjoin the Triangles in the next. Fig. 21.—(_a_) Hexagon Surface Pattern, probably derived from Fig. 11 (_b_), by drawing straight lines between the points of each of the Chevrons. (_b_) The same as (_a_), but with bars instead of lines, and having the Hexagons shaded. The variations in the practical application of the chevron patterns, which have been described above, to the decoration of the sepulchral pottery of the Bronze Age, are produced in the following ways:— (1) By placing the chevrons (_a_) horizontally, or (_b_) vertically. (2) By making the chevrons of different sizes. (3) By altering the angle of the chevrons, _i.e._ making the points more acute or more obtuse. (4) By shading some parts of the pattern whilst other parts are left plain. (5) By using different methods of shading, such as plain hatching, cross-hatching, dotting, etc. (6) By combining the chevrons with horizontal and vertical lines. (7) By arranging the patterns in horizontal bands of different widths.
